5*1 - 0 = 5
5*2 - 2 = 8
5*3 - 3 = 12
5*4 - 2 = 18
5*5 - 1 = 24
5*6 - 0 = 30
5*7 + 1 = 36
5*8 + 2 = 42
5*9 + 3 = 48

The sequence is the addition of prime number in series from 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37.......
So let’s test it on the given numbers in the series;
2+3=5
3+5=8
5+7=12
7+11=18
11+13=24
13+17=30
17+19=36
19+23=42
23+29=52
29+31=60
So on
so next number in this series is 52, 60

In first series,
5×2+2=12
5×4+4=24
5×6+6=36
5×8+8=48...

In second series
8×3-2×3=18
8×5-2×5=30
8×7-2×7=42
